Method

1. Place the chocolate into a microwave safe bowl, and melt the chocolate in the microwave in 20-30 second increments until the chocolate is completely melted (around 90 seconds).
2. Remove the bowl from the microwave and pour in the condensed milk and chopped Brazil nuts. Stir until combined, noting it will feel quite dense.
3. Pour the mixture into a parchment lined brownie tin (20x20 cm) and smooth with the back of a spoon.
4. Place it in the fridge for 2-3 hours to set or until the fudge is firm.
5. Cut into 36 small pieces and store in an airtight container in the fridge.
